This frog is very tiny, with a body length of only 3/4 to 1 1/4 inches (1.9-3.2 cm.). The body color may be tan or dark brown, or even gray and has a darker "X" marking across the back.

Even though they are small, it's easy to see the toe pads on the peeper. These are the adhesive pads that enable the frog to climb smooth, vertical objects.

The spring peeper is confined to the woodlands of eastern and northwestern Minnesota.
